FAQs on Addressing modes in 8051 Video Lecture - Computer Science Engineering (CSE)

1. What are the different addressing modes in the 8051 microcontroller?

Ans. The 8051 microcontroller supports five different addressing modes: immediate addressing, register direct addressing, indirect addressing, indexed addressing, and relative addressing.

2. How does immediate addressing work in the 8051 microcontroller?

Ans. Immediate addressing mode in the 8051 microcontroller allows the programmer to directly specify the data to be used in the instruction itself. This means that the data is directly available in the instruction, usually as a constant value.

3. What is register direct addressing in the 8051 microcontroller?

Ans. Register direct addressing mode in the 8051 microcontroller allows the programmer to directly access the contents of one of the internal registers of the microcontroller. The register number is specified in the instruction itself.

4. How does indirect addressing work in the 8051 microcontroller?

Ans. Indirect addressing mode in the 8051 microcontroller allows the programmer to indirectly access the contents of a memory location using a register. The register containing the memory address is specified in the instruction.

5. What is indexed addressing in the 8051 microcontroller?

Ans. Indexed addressing mode in the 8051 microcontroller allows the programmer to access the memory using a combination of a base register and an offset. The base register points to the base address, and the offset is added to it to access the desired memory location.
